“…Observations of developmental toxicity, which includes, among others, increased prenatal mortality, decreased weight, nephrotoxicity, and skeletal abnormalities, are in agreement with pharmacokinetic data, which show that lithium is readily absorbed and distributed in fluids and tissues (Stokinger, 1981). The dose-response curve for lithium toxicity in rodents appears relatively steep (Trautner et al, 1958;Mroczka et al, 1983), and damaging effects occur throughout the dose range. An in vitro study has shown that explanted embryos from rats or mice are vulnerable to primary lithium toxicity in the absence of any confounding maternal factors (Hansen et al, 1990).…”
